MATLAB: How to get a string array without any space when using NUM2STR function ??

Question

For example, I have a number array (including one-digits and two digits):

A=[0:31]'
A =
     0
     1
     2
     3
     4
     5
     6
     7
     8
     9
    10
    11
    12
    ...

and I want to convert it to a string/char array. I tried to use:

S = num2str(A)
S =
  32×2 char array
    ' 0'
    ' 1'
    ' 2'
    ' 3'
    ' 4'
    ' 5'
    ' 6'
    ' 7'
    ' 8'
    ' 9'
    '10'
    '11'
    '12'
    ...
        

However, I want to get a string array with dimension 31×1, and without any space in front of those one-digits, what should I do????

Answer 1

S = ""+(0:31).'
